I have an old netcomm here that does the same thing.
In regard to the REN mentioned above, most modems look to have a REN close to 
zero while they are on hook, as the only load they impose is for the ring detect.

This old netcomm just loads the line to much while on hook, and so every now and
again you have to unplug it and plug it back in to reset it.

Sounds like time for a new modem.....
